High Frequency and High Speed PCB Materials
Special requirements are required for PCB materials in the making of high-frequency PCBs (such as communication, automobile radar, etc.) and high-speed PCBs (such as servos, large computers, etc.). The lower the Dk and Df values of the insulating substrate, the better it is, thus, the surface roughness of the copper conductor must be small, the cross-section geometry of the conductor must be accurate, etc.
